Definitions

  • the invention relates to a cleaning device on rotary printing machines for cleaning the outer surfaces of cylinders, with a cleaning cloth, with a pressure bar for pressing the cleaning cloth against the outer surface of the cylinder, the cleaning cloth being wettable with cleaning liquid and with actuating devices for turning the pressure bar on and off with the cleaning cloth, gripper fingers being provided on the cylinder to be cleaned in a cylinder channel.
  • the object is achieved in that the pressure bar is triggered by a control signal triggered by a lifting element above the level of the gripper fingers after each cleaning cycle, that a curve segment is provided in the area of the gripper fingers on the cylinder that a pivot lever with cam roller on the pressure bar it is provided that in the area of the gripper fingers, the pressure bar is subjected to a pressure force and the cam roller contacts the highest curve section and that the curve segment then has a sloping curve section, so that when the cylinder is rotated further via the cam roller and the swivel lever, the pressure bar after the gripper fingers is positioned over the cylinder width on the lateral surface.
  • An advantageous embodiment of the invention is characterized in that the pressure bar is assigned pneumatic cylinders which generate the pressure force, and that the cleaning cloth is pressed onto the outer surface by means of an elastic profile rail on the pressure bar.
  • a uniform pressing force can be generated via the pneumatic cylinder, so that the profile rail can carry out an exact cleaning of the surface of the cylinder using the cleaning cloth.
  • the overpressure in the pneumatic cylinders is switched off via the actuating signal and springs on the pressure bar, which lift the pressure bar in the area of the cylinder channel, serve as a lifting element. Switching off the excess pressure can be delayed here, so that the pressure bar has a longer area is slowly lifted off. With this solution, no disturbing blows can occur.
  • the cleaning device 1 can be adjusted to a printing cylinder 2 or by pivoting in its holder 4 on a blanket cylinder 3.
  • the holder 4 is provided on both sides between the machine side frames and enables the cleaning device 1 to be removed.
  • a pressure bar 6 is provided, which extends over the cylinder length.
  • the pressure bar 6 is pivotally mounted on both sides via pivot pin 7 on the support frame 5.
  • the pressure bar 6 receives a number of spring bolts 8 over its length, which are guided in guide bodies 9, 10.
  • a compression spring 11 acts on the guide body 10, so that the profile rail 12 is supported resiliently via the guide body 10.
  • the cleaning cloth 13 is guided over the pressure bar 12.
  • the nuts 14 on the spring bolts 8 allow adjustment of the spring travel and limits the spring travel when they are in contact with the pressure bar 6.
  • a plurality of gripper fingers 17 are provided on a shaft 16 over the length of the printing cylinder 2, which cooperate with a gripper pad 18.
  • the gripper fingers 17 project beyond the lateral surface 19 of the printing cylinder 2, as shown in FIGS. 1 and 2.
  • the outer surface 19 of the printing cylinder 2 can be covered with a film that is cleaned by the cleaning device.
  • pivot levers 20, which carry cam rollers 21, can be fastened on one or both sides.
  • two cam segments 22 are attached to the pressure cylinder, on which the cam rollers 21 can roll during the rotary movement of the pressure cylinder 2.
  • Pneumatic cylinders 23 are attached to the support frame 5, the piston rods 24 of which press the pressure bar 6 downward about the pivot pin 7 when pressure medium is applied via rollers 25.
  • the rollers 25 are fastened to the contact strip 6 via roller pins 26 (FIGS. 2 and 3). If the excess pressure in the pneumatic cylinders 23 is switched off, the pressure bar 6 is moved back into the position shown in FIG. 1 by tension springs 27 and thus the profile rail 12 with the cleaning cloth 13 is lifted off the outer surface 19.
  • the tension springs 27 are stretched between pins 28 which are fastened to the support frame 5 and pins 29 which are fastened to the pressure bar 6.
  • 6 threaded bolts 30 are provided on the pressure bar, which support adjusting nuts 31, the threaded bolt 30 being freely movable in a slot 32 in the pivoted-down position of the pressure bar 6 shown in FIG. If the pressure bar 6 is pivoted into the position shown in FIG. 2, the adjusting nuts 31 sit on the support frame 5 and thereby limits the pivoting movement of the pressure bar 6 in the direction of the lateral surface 19 of the pressure cylinder 2.
  • the control signal for the control of the cleaning device can be given by a known angle encoder, which is attached to the pressure cylinder 2, for example.
